The tails from this process report to the pyrite flotation circuit where pyrite is reactivated ( the depression effect is reversed so that it will float), typically using potassium amyl xanthate (PAX). The goldcontaining pyrite concentrate then reports to the cyanidation circuit for gold leaching and recovery (Benson et al., 2007; Akop, 2014).

Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.
